Improved artificial fuel



UNITED STATES PATENT OFFICE.

EDMUND SHARPE, OF PARIS, FRANCE.

IMPROVED ARTIFICIAL FUEL.

Specification forming part of Letters Patent No. 54,832, dated May 15,1866.

To all whom it may concern:

Be it known that I, EDMUND SHARPE, of Paris, in the Empire of France,have invented certain new and useful Improvements in Artificial Fuel;and I do hereby declare that the following is a full, clear, and exactdescription of my process for preparing the same.

The principal object of my invention is to utilize the peat which is soabundant in some countries, and where it cannot be used in its naturalstate for various reasons.

The principal components of my artificial fuel are peat in its naturalstate mingled with anthracite and bituminous coal in a proportionvariable according to the nature of the peat employed and their degreesof combustibility.

To obtain good artificial fuel it is necessary that these ingredients bewell cleaned by Washing. After this operation they are crushed togetherand mingled by the usual means. They are then cast in a pit, whence theyare conducted into a machine for making artificial fue1forinstance, themachine known as Mazelines, or Evrards, or others. As these ingredientsare fed into the trituratingmachine a valve regularly supplies thecement necessary to eifect their agglomeration, which is the coal-tar,dry or liquid. The artificial fuel fabricated in this manner can beemployed immediately upon its delivery by the machine.

By these means the peat can be classed among the good fuels. It gives acalorie and duration to the fire, rivaling with the good coals, of whichit has nearly the density.

The cinders and ashes produced by the combustion of this artificial fuelare less than those produced by the coals.

The price of this artificial fuel being inferior to the price of coal,my process can be employed with great success in all countries Where thepeat is abundant.

The composition which I found to answer wellis asfollows: peat,fifty-fiveparts anthracite, twenty parts; bituminous coal, fifteenparts, and coal-tar ten parts, making in all one hundred parts.

Having thus fully described my invention and the manner in which thesame is or may be carried into effect, I claim The herein-describedartificial fuel, consisting of peat, anthracite, and bituminous coal,with a coal-tar cement, combined in the proportion and in the mannersubstantially as set forth.
